My sister teaches elementary school, yesterday was the last day of classes for her school. Anyway this story she told me was too funny so I have to share it:

They held a tornado drill the last full week of school. One of her kindergartners asked why they had to get under their desks. She said because during a tornado there might be broken glass. So the kid looked up at her and she said you could see that he was thinking really really hard. He then says, "Broken glass? So we might cut ourselves. If we cut ourselves there will be blood. And blood equals vampires!" Then he went back and did the exercise the way he was supposed to. She had to laugh at the idea that you shouldn't worry about the tornado tearing the school down, the real danger in the kids mind was the vampires!
